    I'm trying to format my disk due to an error with boot camp. However, I cannot push the erase button as shown below. Anybody have any idea why this could be happening?

    You cannot choose erase because you did not boot from the DVD ...

    To clarify what r.j.s. said, you can not erase or format the disk your Mac is booted from. To erase/format the internal hard drive you need to boot from your OS X disc (CD or DVD), from there you can erase/format install the OS.
